lvm snapshot have a big impact on performance, so they should be used temporary, like for backup. Also when you remove the snapshot, you need to re-read and copy data from the snapshot to main lvm. They are a new lvm snapshot format (using dm-thinp), which work fine. (thin reservation, using some kind of cow with metadatas,...) But it's not working in a cluster for now. ----- Mail original ----- De: "Stefan Priebe" <[email protected]> À: "Michael Rasmussen" <[email protected]> Cc: [email protected] Envoyé: Mardi 6 Août 2013 19:55:35 Objet: Re: [pve-devel] LVM no snapshots?

Thanks, i just started to setup a small proxmox home server where i don't have any storage server just disks in my systems and thought i could use snapshots with lvm.
